Chinese lunar rover is part of the third "Moonlit Night" with the same drive unit malfunction

A few days ago received an official confirmation that the problem moonwalker "Yutu" is a problem with the control circuit of the drive unit. As previously reported, it is this problem has led to the fact that the rover mast-sensitive "weather" on the moon communication systems can not properly folded in a box heated.

the mast "Yutu" is a system of communication, as well as cameras for shooting. All this must be folded with the command from the ground, getting into the housing with heating (in case the temperature falls below 40 degrees Celsius). It is worth mentioning that during the lunar night the temperature drops to minus 180 degrees Celsius.

Furthermore, the problem with a drive unit leads to the fact that it becomes impossible to control the position of the solar panels. With the appropriate control system solar panels installed in a position where they receive maximum solar energy.

It is worth mentioning that after the second lunar night, which rover spent without the possibility protect critical systems from the effects of low temperature, the unit "woke up". But, as it turned out, "Yutu" unable to move because of problems with the drives. Observations were carried out now only places because the panoramic and infrared equipment moved lower temperature is normal. In addition, the "survivors" and radar.



The problem with the drive unit in the end does not resolve, and re-enters lunar rover on a moonlit night without the necessary protection of temperature-sensitive systems. Hopefully, after the third of his "night" on the moon rover "wake up."
